Air Throttle slow to respond

[George Lowry]

Jay,

You are correct. When I first converted to an air throttle on my GM bus
conversion, I did not know about the need for reduced pressure and fed
full pressure to it. It was so sensitive that you could not hold a
steady rpm. I reduced it to 60 psi and it worked great. A friend had
used an adjustable regulator, such as used on a paint spray rig, located
at the driver's station so he could regulate the pressure. When leaving
a toll station or inspection station, he would lower the pressure down
to about 25 psi so he would not smoke nor be too loud, then crank it
back up when on the road.
